Patent 3,293,840 WICKLESS VERTICAL TYPE SPINNING RING Andrew J. Wayson, Needham, Mass., assignor to Merriman, Inc., a corporation of Massachusetts Filed Oct. 22, 1965, Ser. No. 501,826 4 Claims. (Cl. 57-120) 1T his invention relates to the textile industry and is particularly concerned with vertical type spinning and twisting rings. When the term spinning ring is used hereinafter, it will be understood to include twisting rings, both of which function in an identical manner.

The invention is further concerned specifically with means for transmitting the lubricant, usually oil, to the exposed surfaces of a spinning ring made of porous metal. Such porous metal rings are well known in the trade and have come into extensive use in the last decade.

When the term vertical spinning ring is used herein, it is intended to mean that type of ring in which the traveler is hooked over the top and bottom of the ring as distinguished from the horizontal type ring in which the traveler is hooked under oppositely extending flanges of the ring. The term vertical type ring also includes that type of ring known as a conical ring which differs from the conventional vertical type principally in its vertical cross-sectional configuration. The conical type ring is substantially wider at the top than at the bottom, whereas the conventional vertical ring is generally of uniform horizontal width.

The ring as disclosed hereinafter as illustrative of the invention is of the conical type, but it will be understood that the ring dimensions may be varied at will so long as they are adequate to incorporate therein the construction hereinafter described and claimed.

The major problem in the use of porous metal spinning rings is that of transmitting the oil simultaneously to interior spaces, continuous or intermittent, within the entire circumferential body of the ring so that the oil may then be taken into the ring by capillary action and transmitted through the ring body to the exposed surfaces. In this manner, a continuous oil film is provided on the surface of the ring on which the traveler slides, thereby to lubricate the traveler and minimize wear.

Heretofore the most commonly used method of transmitting oil to a porous metal spinning ring was by means of a circumferential groove in the outer surface of the ring in which groove resided a wick covered and held in position by a surrounding ring holder. The ends of the wick received oil from any suitable source and the oil was then conveyed by capillary action through the wick around the ring and transmitted to the wall of the groove whence it was absorbed by the ring and distributed to the ring surface.

The present invention contemplates a novel ring structure which will not only eliminate the need for a wick but also will provide for simplified means for mounting the ring on the ring rail.

The invention includes a groove in the upper surface of the ring which is covered in suitable manner leaving a circular channel of substantial dimensions capable of holding more than enough oil to supply the lubricating needs. Extending downwardly from this circumferential channel at frequent intervals are a plurality of generally vertical holes, each of which is maintained in filled condition with oil supplied from the channel. These holes are of such frequency and size as to be capable of supplying enough oil through the body of the porous ring so that all surfaces of the ring are continuously supplied with an oil film for lubricating the traveler.

The details of the invention Will become more apparent as the description proceeds with the aid of the accompanying drawings in which:

FIG. 1 is a plan view of a section of a conical type spinnrng ring supported by a split holder also shown broken away. The width and curvature of the ring in this figure is exaggerated to facilitate illustration; and

FIG. 2 is a vertical section of the ring and a portion of the holder taken on the line 22 of FIG. 1 to enlarged scale. A portion of the ring is in perspective showing the channel and vertical holes.

In FIG. 1, the vertical type spinning ring, which in this instance is shown as a conical type ring, is indicated at 2. A split ring holder for supporting the ring on a spinning frame is shown at 4 with the split ends being illustrated at 6 and 8. The holder may be carried by and afiixed to the ring rail 9' in conventional manner.

In FIG. 2, it will be seen that the ring 2 has a circumferentially extending exterior groove 10 which cooperates with the holder 4. The groove 10 and holder 4 make a close fit with one another. There is sufiicient flexibility in the holder so that when the screw 12- at the split 14 is removed the holder ends 6 and 8 can be sprung apart far enough to permit the insertion or removal of the ring.

Any convenient source of oil supply may be provided. As shown in FIGS. 1 and 2, there is an individual silo 16 which feeds oil downwardly to the passage 18. This passage extends through the holder 4 to connect with an aligned passage 20 extending inwardly from the wall 22 of groove 10 to the interior of the ring. Another passage 24 extends upwardly from passage 20 to terminate in the circumferentially extending groove 26. This groove is relatively wide and may be of any convenient depth. The exact dimensions are not important. The groove or channel 26 is rabbeted at 28 and 30' to receive a cover plate 32. This plate may take the form of a flat metallic ring, for example, or it may be of other suitable material which is impervious to the passage of oil. The channel 26 extends about the entire circumference of the ring 2. Extending downwardly from the channel into the body of the ring are a plurality of vertical holes 34 which are preferably uniformly spaced about the channel 26. The dimension of these holes is not critical except that they should be of sufiicient frequency and depth so that oil therein will be readily transmitted through the porous ring to provide a proper oil film on all of the exposed surfaces of the ring.

The shape and size of the holes 34 may be varied to control oil distribution. For example, the holes instead of being cylindrical as shown could be in the form of inverted cones, thus to present a larger area exposed to the oil at the top and less at the bottom. In this'way, more or less oil could -be fed to the wider upper portion of the conical ring as might be deemed necessary by the user. Again, the viscosity of the oil could be varied and related to the interior surface of the holes 34 to give the oil distribution required.

By the foregoing construction, a ring has been provided that is relatively inexpensive to manufacture by conventional processes. The only machining required is the turning of groove 10 and the drilling of holes 34. The need for a wick is eliminated, thus simplifying the replacement of a worn ring. Additionally, the holder may be made of lightweight construction without sacrificing required strength and rigidity.

It is intended to cover all changes and modifications of the examples of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.
